What does everyone think about these types(i.e. projection) of kits? I am looking to avoid all the sensors and wiring of say a factory throttle body or multi port setup. The less complicated the better. I know it would probably be cheeper to strip a junkyard motor but I'm not looking for that. Thanks.

I hated my projection. The fuel pumps were fragile, the adjustments had too much overlap, and if it breaks in bumfug you can't get parts...I went back to a carb and I'm happy (unless I'm pointing straight down) : ) ... factory efi is the way to go. imho

An EFI system is only as good as the info it gets. More sensors is better! Modern EFI has sensors for air intake temp, fuel temp, crank position,cam position. plus the usual throttle position, mass air and O2 , water temp ,ect

I run the old 2d projection. Alot of people have had problems with them. Mine is far from perfect but then again its 20x better then my q-jet ever was as far as angles go. The q-jet had tons more power though. My only regret is not getting a 4 barrel system (350). I would definatly do it again for $500

Not a huge fan of Projection, but it works well for some people. For what it is, its a good system. If you get one, carry a spare injector, invest in a good fuel filter, and throw away the fuel pump that comes with it. The pumps that I've seen work well with it are Airtecs (sp) inline pumps and stock Chevy TBI intank pumps (my preference, if you go this route get an AC Delco pump).

You cant beat GM TBI for relaiblity and simplicity. You can probably take all the parts you need from a junkyard truck for a couple hundred and when something goes, the local partshouse will have what you need. Grab the factory harness too, those painless harnesses are not necassary. The factory ones are easy to hook up. I have a 91 TPI setup waiting to go on my Blazer. Does anyone here burn chips? I'm also looking for a distributor for it too.

The best place for the projection is on the shelve at the store! I tryed one and did not care for it at all. The only efi I will run is TBI. I put in my 82 motor home and also on my 351 EB. My 89 chevy(235,000) and 91(265,000mi) both had it and I was never let down and one other guy at work had 455,000 on his 89 and it is still going! Run the entire system from a stock truck and you will love it.

I had the Holley 4di that you used a laptop to tune. F-ed around with it for over a month and it sucked big time. If you have a motor with a larger cam it messes up the fuel mix, and holley will always run a little rich. Mix these two with moly rings and you will start dropping cylinders.

My friend has the analog style on his worked 396 and it never misses a beat. Sometimes less is better.

Yea $2,000 was high, but I've had the ProFlow for over five years and no problems. I like how I can adjust spark or fuel for different RPM and vacume on the fly with thier key pad.

What engine is it going on? Think stock. 20r to 22re? 258 to 4.0? 5.7 to 5.7?

Not just because it is cheaper, but more reliable with more help files and man pages on.

It's going on a 350 chevy in a toy pickup. Thanks for the responses, I changed my mind and just purchased a TPI system of a camaro. Hope it is not too hard to figure out!

Scott, the best thing you can do now is buy a Helm manual for the Camaro. Best place I've found for them is www.factoryautomanuals.com.

Holley Cammander 950!! There is no longer a projection kit made. I love my Commander system. It is controlled by a lap top which is easy to calibrate. Insted of the external pump though I switched to a late model tank and used a Walbro performance fuel pump(in Tank) with no problems. This kit was also easy to install.
